Ordinarily you would use Heron's Formula to find the area of a triangle with sides measuring 
, 
, and 
.
(s\ -\ b)(s\ -\ c)})
where 
is the perimeter divided by 2, that is:
Step 1: Substitute , , and to calculate
Step 2: Substitute , , , and to calculate the area.
However, the first statement in your problem is false. That is to say it is not true that a triangle has sides 18, 29, and 47. That is because a three-sided figure is not a triangle unless the sum of the measures of the two short sides is GREATER than the measure of the longest side. Not having a triangle, the question "What is the area..." is absurd.
